GORN-SHELLER.

Specification of Letters Patent.

Patented June 9, 1914.

To all whom itmay concern Be it known that I, EUGENE CLAUDE, a citizen of the United States, and resident of Somonauk, county of Dekalb, and State of Illinois, have invented certain new and useful Improvements in Corn-Shellers, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to corn shellers of the type shown in the Patent No. 998,411? granted to Plin C. Southwick, July 18, 1911.

The object of the invention is to provide improved means for controlling the discharge of cobs from the shelling chamber and an embodiment of it is hereinafter described and is illustrated in the accompanying drawings, in which-- Figure 1 is a detail plan view of a corn sheller, some of the parts being broken away; Fig. 2 is a detail section on the line 2-2 of Fig. 1, and Fig. 3 is adetail section on the line 33 of Fig. 2.

A portion of the body of the sheller is represented at 10. The discharge end of the cylinder is indicated at 11 and the cylinder barrel at 12. 'As in themachine shown in the Southwick patent there is anupright extension, 13, of the shelling chamber adjacent its discharge end. A cob discharge opening is at the end of this extension and is normally closed by means of a damper 15 hinged at its upper edge to the extension 13, or more properly to a hood 16 projecting from the end of this extension. A pivot rod 17 of the damper 15 is journaled in the side walls of the hood 16, and to it there is fixed a laterally projecting arm 18 carrying a This weight may take preferably channeled to bottom bars 20 and 21 movable weight 19. the form of a roller, fit between top and of the arm 18.

The damper 15 and arm 18 are so related that when the former is closed the latter is inclined downward toward its free end. As the damper opens, responsive to the pressure of the cobs seeking exit, the arm 18 is raised and as soon as its free end passes above the horizontalgthe weight 19 tends to move inwardly toward the pivot 17 andthis movement occurs as soon as the elevation becomes sui'ficient for gravity to overcome the frictional resistance. Preferably the roller fits freely between the top and bottom members of the arm 18 so that there is but little resistance to its movement.

In machines of this type it is desirable that there be some impediment to the free discharge of the cobs and the damper is pro vided for this purpose. When in a vertical position the damper does not sufficiently retard the cobs unless weighted. WVhen. the weight is applied directly to the damper, as in the Southwick patent, it becomes increasingly effective as it swings away from the vertical position and tends to impose too great an obstacle to the movement of the cobs. By the construction herein shown and described this tendency of the weight to increase with its outward movement is obviated automatically by the inward movement of the roller 19. Should the discharge of cobs decrease in volume and thus permit the damper to close, the roller immediately returns to the outer end of the arm. By this construction, the parts being properly proportioned, there is provided a substantially uniform resistance to the discharge and the action of the machine is thereby substan-.

tially improved.

I claim as my invention,

1. In a corn sheller, in combination, a:

shelling chamber having a cob discharge port, an outwardly opening damper covering the port yieldable to the pressure of the material, and means for resisting the opening movement, such resistance being ar ranged to decrease as the damper moves outward.

2. In a corn sheller, in combination, a shelling chamber having a cob discharge port, means for yicldingly opposing the discharge of material through the port, the opposing force of such resisting means decreasing as the quantity of material increases.

3. In a corn sheller, in combination, a shelling chamber having a cob discharge port, an outwardly swinging damper covering the port, an arm projecting laterally from the pivotal axis of the damper and being downwardly inclined when the damper lng the port an arm pro ecting laterally I from the pivotal axis of the damper and being downwardly inclined when the damper is closed, and a Weight in the form of a roller 10 lob'sel'y running on the arm. i
